Oil light turns on when stopping

Welcome to 2CarPros.

Because of the mileage, I recommend that you check oil pressure with a mechanical oil pressure gauge. Most parts stores will lend or rent the gauge to you. All you do is remove the electric oil sending unit and screw the mechanical one in its place. Once you start the engine, you will see how much pressure you have at idle.

Now, if you are not hearing any ticking or knocking when the light is on, that is a good thing. However, we need to confirm it isn't truly a pressure issue.

Here are the manufacturer's specs for minimum pressure requirements before the light turns on and at 2500 rpm's

One last thing, make sure the sensor you replaced is the one next to the oil filter and there are no leaks. Also, make sure the oil is clean and full and you have a good quality oil filter installed.

Let me know what you find.

Welcome back:

Good. Then we need to check the actual pressure to determine if the sensor and system are working properly or there is an internal engine issue. The only way to be sure is is using a mechanical gauge. Low pressure can be caused simply from bearing wear, a weak oil pump, or a partially plugged oil pump pick up screen. Once we determine the actual pressure is the problem, then we can move ahead.

Let me know if you have questions or need help.

Welcome back:

If there are no leaks at the sensor, then that's a good thing. I hate to say it, but at this point we really need to check pressure using a mechanical gauge. It is really easy to do. If you go to a nationally recognized parts store, they will lend or rent you the gauge. Then, simply remove the electric sensor you installed and screw in the mechanical one and start the engine.

I'm here to help, so don't be worried about the process. I will help.

Take care,
Joe
